Title:
iwlwifi not loading on kernel 5.4.0.37.40
Status in linux package in Ubuntu:
Incomplete
Bug description:
I have a lenovo thinkpad E550 that has had kubuntu installed starting with
18.04, now updated to 20.04, I never had problems with wifi until last kernel
update.
If I boot with 5.4.0-33.37 the wireless connection acts normally, it's mostly
stable and I have no major issues.
If I boot with 5.4.0-37.41 there is a message like this and the wireless
interface is not activated:
[ 16.227170] kernel: iwlwifi 0000:04:00.0: enabling device (0000 -> 0002)
[ 16.227328] kernel: iwlwifi 0000:04:00.0: HW_REV=0xFFFFFFFF, PCI issues?
[ 16.275802] kernel: iwlwifi: probe of 0000:04:00.0 failed with error -5
There are similar issue with previous releases, but none seem to have fixed
the problem, some of the more informatives (apparently it's either a kernel
issue fixed with kernel 5.6 or a firmware loaded incorrectly):
